CRUSHING OR GRINDING MACHlNE.

SPECIFICATION forming-part of Letters Patent No. 507,140, dated October24, 1893. Application filed September 27, 1892. Serial No. 447.077. (N0model.)

To all whom it may concern.-

, Be it known that I, CORNELIUS KIMPLEN, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Crushing or GrindingMachines, of which the following is a specification, reference being hadto the accompanying drawings, in which- Figure 1 is a side elevation.Fig. 2 is a top or plan view of the lower bed-plate. Fig. 3 is a centrallongitudinal vertical section. Fig. 4 is an enlarged detail, being acentral longitudinal vertical section of the grinding mechanism. Fig. 5is an enlarged detail, being a back view of one of the grindingsections. Fig. 6 is a cross section on line w-x of Fig. 5; and Fig. 7 isan enlarged detail,

showing one of the spoons and the method of securing it to therunning-head of the mill.

My invention relates to machines for crushing or grinding stone, bone,or other similar substances, and is in many respects similar to the millshown in Patent No. 281,887, granted to me July 24, 1883.

I The object of my invention is to improve the construction andoperation of mills of the above described class, which object Iaccomplish as hereinafter specified and as illustrated in the drawings.

That which I regard as new will be pointed out in the claims.

In the drawings,1, indicates a bed-plate, which supports thevarious'parts of the machine. The bed-plate l is annular in shape, andis provided with a central cross bar 2, as best shown in Fig. 2. p 3,indicates a number of vertical columns which areplaced at suitablepoints upon the bed-plate 1, and support another bed-plate 4 in ahorizontal position, as best shown in suitable bearings 16 and 17,resting upon th upper bed-plate 4. The bearing 16 is located Figs. 1 and3. The columns 3 are preferably five in number, and are arranged asshown in Fig, 2. The bed-plate 1 is provided at a suitable point on itsupper surface with a removable segment 5, which is of about half thethickness of the bed-plate.

6, indicates parallel bars, which at one end are secured to theremovable segment 5 and extend across'the bed-plate, as best shown inFig. 2, theirother ends moving in suitable bearings 7 secured tot-he-und-er side of the cross piece 20f the'bed plate 1. Bythisconstruction, the segment 5 is adapted to be drawn away from theremainder of the bedplate in a straight line. In order to move thesegment 5 to or from the bed-plate, the ends of the bars 6 adjacent tothe segment 5 are cogged on their under sides to form racks, as bestshown in Fig. 5.

8, indicates a cogged pinion, two of which are mounted upon a shaft 9mounted in suitable bearings in the bed-plate 1, and extending acrossthe bed-plate in a direction at right angles to the bars 6. The pinions8 are so placed that one of them will intermesh with the rack upon eachbar 6.

The shaft 9 is made of such length that its ends will project a shortdistance beyond the periphery of the bed-plate 1, and such projectingends are squared, as shown at 10 in Fig. 1. By applying a wrench orlever 11 (see Fig. 3) to one or both of the ends of the shaft 9, theshaft may be rotated, therebyl moving the segment 5 into or out of itsplace in the bed-plate 1, as the case may be. I

One of the columns 3 is mounted upon the removable segment 5 of thebedplate, as shown in the-drawings, and that portion, 12, of the upperbed-plate 4 immediately over the removable segment5 is detached from theremainder of the upper bed-plate 4 and rests upon the column 3 upon saidsegment 5, as best shown in Fig. 1. By this construction, when thesegment 5 is moved, the segment 12 of the bed-plate 4 willalso besimilarly moved. When the machine is being operated, the segment 5 maybe rigidly secured in place by means of bolts 13, and the segment 12 maybe firmly secured in place by means of bolts which pass through cars 14,cast at suitable points in the bed-plate 4 and segment 12, as

shown in Fig. 1.

15, indicates a shaft, which is mounted in over the column 3 which restsupon the removable segment 5, and the bearing 17 is 10- cated at adiametrically opposite point upon i I i ferred to, being somewhatcircular. A delivery tube 52 is provided, which opens into the upperpart of the casing 51.

53, indicates a cover which fits over a suitable opening in the upperpart of the casing, through which access may be had to the interior ofthe casing. Thecasing is of somewhat greater diameter than therunning-head 33, and is adapted to receive the powdered stone or othersubstance after it has passed from the grinding sections 35. Thepowdered substance will then be carried by centrifugal force around theinterior of the casing 51 to the outlet tube 52.

In order to cause the crushed substance to move more freely around thecasing 51 to the outlet tube 52, the running-head 33 is provided on itsperiphery with spoons 53, which are radially secured in the running headby means of plates 54 which are arranged in mortises 54 in the innerface of the runninghead, as best shown in Fig. 7. If desired, the spoons53 and plates 54 may be made separate from each other, but I prefer tomake them integral with each other, as shown in Fig. 7. Besidesmortising the plates 54 in the running-head 33, they may be furthersecured therein by means of bolts 55, as shown.

When the running-head is in operation, the spoons 53 will aid incarrying the crushed or ground substance around the interior of thecasing 51, and will serve to expel any unbroken fragments or pieceswhich may have passed through the grinding plates without being crushed.They will also cause a draft through the casing, by which all dust willbe carried out.

The shaft 15 is provided with a pulley 56,

by means of which it may be rotated, andv with a fly wheel 57, as shownin Fig. 3.

The movable bearing 23 and weight 62 perm'it the grinding plates to beforced apart, as would be necessary if some extraordinarily hard bodyshould fall into the hopper, to prevent breakage of the mill,substantially as described in my former patent hereinbefore referred to.

That which I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a frame 47, an inner crushing plate 48 and anouter grinding ring 49, of a supporting head 33 having a flange 43, aninner crushing plate 34 having a peripheral flange 37, an outer grindingring having a recessed part with which interlock the said flanges on thesupporting head and crushing plate, and devices for securing the outer.grinding ring to the supporting head to clamp the inner crushing plateto said supporting head, substantially as described.

5. The combination with asupporting head or plate, having an annularrecess 42 and flange 43, of a crushing plate 34 mounted thereupon, saidcrushing plate having peripheral flange 37,a grinding ring composed ofsegments 35, each of said segments having a recess 41, adapted to clampthe flanges 37 and 43 together, and devices for securing said sectionsin place, substantially as described.
